Pentagon to Unveil Open-Source Software for Wireless Innovations
In an effort to foster innovation in wireless communications, the Defense Department is preparing to launch an open-source software stack aimed at empowering both military and commercial users to create bespoke network solutions.
The Pentagon’s FutureG office will make the inaugural release of the Open Centralized Unit Distributed Unit (OCUDU) radio access network project available on GitHub this April, as announced by the department on Sunday.
Following this release, the OCUDU codebase will be accessible to developers, enabling them to construct new functionalities that have the potential to revolutionize both current 5G and forthcoming 6G networks.
This initiative represents a collaboration between the FutureG office, overseen by the Office of the Under Secretary of Defense for Research and Engineering, and the non-profit National Spectrum Consortium.
The project aims to dismantle existing barriers within the telecommunications sector that hinder innovation, according to Tom Rondeau, the principal director for the FutureG office, during an interview with DefenseScoop.
“My perspective is that we require a transformation akin to what Linux accomplished for the Internet and what Kubernetes achieved for cloud computing,” Rondeau explained.
“We need a similar paradigm shift to distribute the burden of infrastructure and promote competition where it can create meaningful change.”
Currently, the global landscape of 5G networks is predominantly controlled by a small number of major players, including Huawei from China, Ericsson from Sweden, and Qualcomm from the United States, which market their systems as proprietary products.
Despite the push towards Open Radio Access Network (Open RAN) solutions, vendor lock-in continues to restrict substantial customization of hardware and software applications, thereby deterring new entrants into the field.
“The developer community plays a pivotal role in bringing these use cases to fruition and crafting the surrounding applications and infrastructure,” Rondeau stated.
“However, they are largely excluded from pioneering innovations in this domain, as even Open RAN solutions frequently lack complete access to all components.”
Following the announcement of the project last year, the National Spectrum Consortium contracted DeepSig and its collaborator Software Radio Systems (SRS) in September 2025 to create the first version of the OCUDU software.
Within the span of six months, these companies have developed a codebase representing a fully functional and downloadable RAN stack.
The objective is to furnish developers with a virtual environment conducive to the creation, testing, and deployment of custom wireless technologies, as articulated by Mari Silbey, chief program officer at the National Spectrum Consortium.
“The software stack will enable developers to build upon fundamental radio functions rather than commencing their efforts from square one,” Silbey informed DefenseScoop in an interview.
The Pentagon and National Spectrum Consortium are collaborating closely with the Linux Foundation, which will oversee the software’s management post-publication. To expedite development, an OCUDU Ecosystem Foundation has been established, bringing together industry and academic members.
In a recent announcement, the Linux Foundation revealed that 47 organizations have joined as founding members of the OCUDU Ecosystem Foundation, encompassing prominent telecom firms such as Ericsson, Nokia, Verizon, and AT&T, alongside specialized vendors like NVIDIA.
“We now possess a foundational software framework, along with a coalition comprising large and small enterprises, universities, research institutions, and multiple governmental bodies committed to further development,” Silbey remarked.
While OCUDU promises to benefit the wider industry, its implications could significantly enhance the Defense Department’s network operations.
Historically, the Pentagon has had the option to procure tailored telecommunications systems from suppliers. Recently, the industry’s focus has shifted towards the more lucrative consumer market centered around 5G, diminishing the incentive to develop customized solutions for the Department of Defense, Silbey indicated.
“In order to gain new features or functionalities absent from consumer product lines, the DOD aims to broaden technological access to spur innovation,” she asserted. “This endeavor began with Open RAN and is further advanced through OCUDU.”
Rondeau noted that understanding various applications capable of operating on a radio access network is of particular interest to the Pentagon.
Historical projects overseen by the FutureG office have demonstrated applications that enhance energy and spectrum efficiency—critical elements in the Pentagon’s ongoing efforts to advance spectrum sharing with commercial entities.
To facilitate the identification and examination of military-specific applications stemming from OCUDU innovations, the FutureG office is collaborating with both the Naval Information Warfare Center Pacific and the Georgia Tech Research Institute, Rondeau added.
An essential focus will be to explore capabilities that optimize the Department of Defense’s operations within the electromagnetic spectrum, such as artificial intelligence-fueled network management.
Arpit Joshipura, general manager of networking, edge, and the Internet of Things at the Linux Foundation, asserted that positioning customized AI models nearer to the end-user—be it an individual, defense mechanism, or base station—can automate functions such as beamforming and network traffic management.
“The AI component introduces what I refer to as ‘magic,’” Joshipura commented in an interview. “It enables the most efficient utilization of the limited resources at hand in a network, especially in scenarios characterized by conflict or disasters where connectivity is compromised.”
Upon the initial release of the OCUDU software, the FutureG office plans to continue issuing updates over the next six months, Rondeau noted. By the conclusion of the three-year initiative, the Pentagon anticipates achieving a minimum viable profile of a carrier-grade network solution.
“My aspiration is to cultivate a marketplace filled with competitive ideas,” he remarked. “I envision a landscape where entities can approach this with more than just hyper-specialized knowledge, fostering a friendly and open development ecosystem that generates ideas, tests them, and, crucially, enables data extraction from various components of the processing stack in a RAN to inspire new concepts.”
